The iCarly Crew performs sketches on their show that spoof those on "Late Night with Jimmy Fallon," which the host finds so impressive, that he invites them on his show for a rare live performance. Thanks to some of Gibby's usual misfortune however, the cast of both shows almost gets in trouble.

When Sam's laptop gets stolen, the iCarly gang tries to help track down the thief. Meanwhile, Spencer can't visit his favorite arcade unless he's accompanied by a child. His luck turns when Guppy needs a babysitter.

Carly is sad when her father cannot escort her to a military dance; Sam and Spencer fix a motorcycle; Gibby gets his head stuck in an "artificial head machine" (because he sold his first one at the pawn shop); Freddie gets a new phone.
